The biggest problem encountered by 20mm Ultra-thin Style Back-lit LED Panel Light is heat dissipation, and the LED is the same. 20mm Ultra-thin Style Back-lit LED Panel Lightt consumes a lot of power, and a considerable part of the energy is wasted on heating. Fever can cause the following problems:

1. Wavelength drift

Wavelength drift will cause problems in color correction. The wavelength drift of 20mm Ultra-thin Style Back-lit LED Panel Light is relatively large at low temperature and high temperature. According to the experimental data, when the temperature changes by one degree, the wavelength changes by 0.2-0.3nm.

2. Reduced output brightness

Every degree Celsius temperature change results in a 1% change in output brightness, among which the red light is most affected. From 180% brightness at -40 degrees to less than 50% at 120 degrees, that is to say, the brightness of the red light is reduced by nearly two-thirds. Relatively speaking, the brightness of the blue light and the green light are not so affected by temperature, especially the blue light. There is a problem when the temperature rises, the brightness emitted by different colors of 20mm Ultra-thin Style Back-lit LED Panel Light is not the same.

3. The life of 20mm Ultra-thin Style Back-lit LED Panel Light is shortened due to temperature rise

According to the data of a laboratory in the United States, when the junction temperature rises from 63C to 74C, the life of the LED decreases from 36,000 hours to 16,000 hours.

4. Too many cooling components lead to higher system cost Too many cooling components lead to higher system cost.

5. Waste energy, increase user cost Waste energy, increase user cost.

So where does the heat come from? From the power supply to the 20mm Ultra-thin Style Back-lit LED Panel Light, to the LED driver, to the adjustable resistor, the heating part includes the LED lamp, LED driver, and LED wiring.
